Removing rows from table model

[jpn]

Looks like the whole model is cleared anyway so how about calling QAbstractItemModel::reset()?

//beginRemoveRows( QModelIndex(), 0, m_Data.count() / 4 );
//for( int i = 0; i < m_Data.count() / 4; i++ )
//    QAbstractItemModel::removeRow( i );
m_Data.clear();
reset();
//endRemoveRows();

//beginRemoveRows( QModelIndex(), 0, m_Data.count() / 4 );
//for( int i = 0; i < m_Data.count() / 4; i++ )
//    QAbstractItemModel::removeRow( i );
m_Data.clear();
reset();
//endRemoveRows();

By the way, QAbstractItemModel::removeRow() implementation does nothing so there is no need to call it.
